Super-fast battery charging could be the Galaxy S9’s secret weapon
We don’t only care about how long a smartphone battery can last, we also want it to charge as quickly as possible so that we’re never out of juice.
Battery size can’t grow significantly in the near future, considering that we’ve reached a sort of peak smartphone design. But the next batch of smartphones coming out should be even more energy efficient than 2017 models, and they’ll feature even better fast-charging battery tech. The Galaxy S9 could be one of them.
